2.1.2 Completable with andThen never completes

See original GitHub issue

This test fails:

Completable.complete()
        .andThen{ Completable.complete() }
        .test()
        .assertComplete()

However this one succeeds:

Completable.complete()
        .test()
        .assertComplete()

This one also succeeds:

    Flowable.just("")
            .flatMap { Flowable.just("") }
            .test()
            .assertComplete()

My understanding is that concating (which is what andThen does?) two completables which complete immediately should complete. I tried:

using awaitForTerminalEvent but it just runs forever in the first case.
.andThen{} instead of .andThen{ Completable.complete() }
Completable.fromCallable instead of Completable.complete() or switching from a Flowable to Completable

You want andThen(Completable.complete()). Note the use of parenthesis and not curly braces. The latter creates a lambda that doesn’t call its emitter.
